IMPROVED MODE OF RAISING SUNKEN VESSELS.

Spccitication forming part ol' Letters Patent No. A15,602, dated lleeinnber 27, ISM.

To (LIZ whom it may Concern:

Be it known that l, UALEB IIAnRlsoN, ol' l\lilwaukee, in the State of \Visconsin, have invented a certain new and uset'ul improvementon means for raising slinken vessels and other bodies in or under the water; and I do hereby declare that the following' is a t'ull, clear, and exaetdesoription thereof, reference being had to the accompanying` drawings, and to the marks and letters thereon.

My invention relates to that class of' means y t'or raising sunken vessels and other submerged bodies where atmospheric or other air or gas is used, and has special regard to the use ot' emnpressed air and the manner otl rendering;` its buoyancyavailable and ellieient.

being a face view ot' the smaller cylinder with the tube and faucet attached thereto.

In each of these figures, where like parts are shown, like marks and letters are used to iudicate the parts.

As is evident, chambers or reservoirs ot" any other shape or form may be used instead ol' holes or outlets Z efproperly controlled by plugs or cocks, are provided. The larger one ol' these holes or outlets is represented as having;v such controlling plug' or valve, and the same kind ot plug or valve may be used in eomiection with tubular projections from thc cylinder, or any other suitable plug may he used to control the smaller openings. The large outlet is the main one that will be used the smaller ones being` only supplemental.

\Yhen the eylinder b is lllled with water and attached to cylinder u, llled with eompressed air, the weight` of the Whole will be such as to sink in the water, and when so prepared they can be lowered down and guided to the vessel or other object by any of the means generally or con'unonly employed l'or loweringand guiding bodies-in water. Having reached sueh vessel or object, and cylinder l having;` been properlyY secured to it,

i the cork or valve between the two cylinders being opened and the cocks or valves of cylinder l heiner also opened lor the escape of the water therein, thc compressed air ot' cylinder u will rush into the cylinder b, forcing out the water nml expanding;y in that cylinder, and when the escape ot" the air through the out-r lets ot'eyllnder i) indicates that the water is the cylinders, and the kind and character ot)` the connections and faucets or valves and their position and relation tothe chambers and to each other can be sneh as will best adapt them to the partimilar object to be raised or to the location, occasion, or other present circumstances.

The drawings represent the cylinder o lo be ofthe least capacity of the two. In this cylinder atmospheric or other air will bel torced to such deereeof con'ipression as will be deemed requisite, the pressure for producing such compression being derived from any ot' the usual sources of power for such purpose. This cylinder, beinf,T tilled with compressed ai and thetaucet or valve closed, :an be attached to the cylinder I), by the tube C, or by any other suitable means. Cylinder b will have such capacity as will allow the eompressed air ot' cylinder u to be expanded therein.

When ready to be passed down to the slinken vessel or other body, cylinder l; will be llled with water, l'or the exit oln which out ot' it, the outlets can be closed and the air then be contined in that cylinder. Cylinder u can then be separated from b and drawn up to the surface t'or further use. In this way such number oi' cylinders or other chambers may be passed down to the vessel or body to be raised until the bouyaney required to elevate such vessel or body is thus given toit.

As will readily be perceived, this manner ot' usingcompresscd air may be extended to submarine armors and such other pieces of apparatus and structures ot' a like character ol", as will allow ot' the use ol' air or gas under such circumstances.

What l elaim as my invention, and desire to secure by Letters Iatent, is-

The raising ot' sunken vessels and other bodies in the manner and hy the means substantially herein recited.
